Myers-Briggs theory is an adaptation of the theory of psychological types produced by Carl Gustav Jung. It is based on 16 personality types, which Jung viewed as stereotypes. They act as useful reference points to understand your unique personality. At the heart of Myers Briggs theory are four preferences. Do you prefer to deal with:

* People and things (*Extraversion* or **E**), or ideas and information (*Introversion* or **I**).
* Facts and reality (*Sensing* or **S**), or possibilities and potential (*Intuition* or **N**).
* Logic and truth (*Thinking* or **T**), or values and relationships (*Feeling* or **F**).
* A lifestyle that is well-structured (*Judgment* or **J**), or one that goes with the flow (*Perception* or **P**).

## Usage

Add this to your `Cargo.toml`

```toml
[dependencies]
mbti = ">=0.1.3"
```

## Examples

Get a function from a MBTI type:

```rust
extern crate mbti;

use mbti::{get_function, Function, Role, Type};

fn main() {
    let primary = get_function(Type::INTP, Role::Primary);
    assert_eq!(primary, Function::Ti);
}

```

Get all the functions from a MBTI type:

```rust
extern crate mbti;

use mbti::{get_functions_from_type, Function, Type};

fn main() {
    let functions = get_functions_from_type(Type::INTP);
    assert_eq!(
        functions,
        vec![Function::Ti, Function::Ne, Function::Si, Function::Fe]
    );
}
```

Get all the MBTI types from a function role:

```rust
extern crate mbti;

use mbti::{get_types_from_function_role, Function, Role, Type};
use std::collections::HashSet;
#[macro_use]
extern crate maplit;

fn main() {
    let types = get_types_from_function_role(Function::Fe, Role::Primary);
    assert_eq!(types, hashset![Type::ESFJ, Type::ENFJ]);
}

```

Get a MBTI types from a set of functions:

```rust
extern crate mbti;

use mbti::{get_type_from_functions, Function, Type};

fn main() {
    let functions =
        get_type_from_functions(&[Function::Ti, Function::Ne, Function::Si, Function::Fe]);
    assert_eq!(functions, Some(Type::INTP));
}
```

Get compatibility between two MBTI types:

```rust
extern crate mbti;

use mbti::{check_compatibility, Compatibility, Type};

fn main() {
    let compatibility = check_compatibility(Type::INTP, Type::INFP);
    assert_eq!(compatibility, Compatibility::Positive);
}

```
